GAS-BURNER.

SPECIFICATION forming part of Letters Patent N o. 748,607, dated January 5, 1904.

Application filed May 23. 1903.

1 To all whom it` may concern;

Beit known that I, ALFRED E. How/ARD, acitizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Gas-Burner, of which the following is a specifcation.

My invention is an improvement in gasburners; and While my burner may be utilized for the purpose of cookingit is especially designed and adapted for the burning of gas in an open fireplace, my object being to provide a burner of this kind which will produce an open fire of a novel and attractive appearance and also to devise a burner of this type in which the maximum amount of heat produced by the burning gas will be thrown out into the room.

My invention consists of the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claims, and shown in the accompanying drawings, in which- Figure l is a perspective view showing the practical application of my device. Fig. 2 is a vertical section through my burner. Fig. 3 is a perspective view showing my burner as seen from below. Fig. Ais a plan View of the top plateof my burner, and Fig. 5 is a perspective View of the horizontal partition.

In the drawings, A represents a gas-pipe having a tip A', secured to the pipe by the collar A2, and B represents a mixing-chamber having the appearance of an inverted bowl carried by the tip A'. A perforated plug A8 is secured on the tip and regulates by size of the perforation the amount of gas fed to the mixing-chamber. In the event that a larger supply of gas is desired the plug A3 may be removed and the device is used without it. Above and supported by the lower mixingchamber B is a bowl-shaped chamber B', the two chambers being connected by a neck formed by the telescoping flanges B2. Air is admitted to the lower mixing chamber B through the V-shaped slots B3, formed in the bottom of the said chamber. Supported by the upper mixing-chamber B' is a shallow rectangular tray or vessel comprising the bot- 5o tom C, having a fiat apertured central por- Serial No. 158,510. (No model.)

tion and upwardly-sloping marginal portions. A slightly-convex cover C extends over the vessel, and the edges of said cover are bent over the edges of the bottom C, as shown at O2, thereby securing an air-tight joint.

The tray or vessel is divided into upper' and lower compartments C3 C4 by a horizontal partition O5. V-shaped notches are cut into the edges of this partition, forming blunt teeth C, which are bent transversely and al- 6o ternately upwardly and downwardly, the downwardly-bent portions resting on the sloping margins 0fthe bottom C and the upwardly-bent portions serving to support the cover-plate C'. A central stub-post CT is 65 threaded into the partition C" and supports the center of the cover, while posts C8 rest on the bottom C and extend through the partition C5 and aid in supporting the cover. The cover has a plurality of perforations C9, and 7o its upper surface is surrounded by a low fence of wire scrollwork C10, though any ornamental border of wire, brass, or other metal can be used. The bottom C has a central opening C11 and an annular depending iiange C12, 75 serving as a short pipe opening into the lower compartment C3 and more effectually mixing the air and gas as they pass through it. Loose asbestos wool D or similar material is heaped upon the cover C', being held there- 8ov on by the border or fence U10.

The pperation of my device is as follows: The pipe A being arranged centrally in an open fireplace or wherever it may be desired t0 use the burner, gas will pass upwardly into 85 the mixing-chamber, and air will be drawn into the chamber through the openings B3. The air and gas will commingle during the passage through the neck B2, and the mixing of the two will continue in the chamber B', go the mixing being further effected by their passage through the throat C11, formed by the flange C12.' The commingled gas and air then spreads through the compartment C3 and passes up over the edges of the plate C5 95 into compartment C4 and through the openings 09, intermingling with the looseV asbestos, and when lighted the dames of the burning gas will intertwine among the mass of asbestos, playing over the top and around loo and means for retaining said material in place, as and for the purpose described.

2. A device of the kind described comprising a shallow vessel having a perforated cover, means for admitting gas and air into the vessel, a wire scrollwork carried by and extending around the cover, and asbestos piled loosely upon said cover.

3. A burner of the kind described comprising a gas-pipe opening upwardly into an inverted-bowlshaped miXingchamber, said maso? chamber having air-openin gs in its lower portion, an upper bowl-shaped mixing-chamber resting on the lower one, a shallow vessel resting onfthe upper mixing-chamber, said vessel having a perforated cover, and a flat, horizontal partition dividing the vessel into upper and lower compartments, said partition having blunt teeth formed on its edges, the said teeth being bent alternately upward, and downward.

4. A device of the kind described comprising a rectangular, shallow vessel the bottom of said vessel having upwardly-sloping marginal portions,a slightly-convexed,perforated cover over said vessel, a horizontal partition arranged in the vessel and having notched edges, a metal scrollwork around the upper edge of the cover, asbestos laid loosely on the cover within the scrollwork and means for admitting gas and air into the vessel beneath the horizontal partition.
